This little DC\/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003c\/span\u003e \u003cspan\u003eThe output is tweaked to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. \u003c\/span\u003e \u003cbr\u003e \u003cbr\u003e \u003cspan\u003eThe PowerBoost 500 has at the heart a \u003c\/span\u003e \u003ca href=\"http:\/\/www.ti.com\/product\/tps61090\"\u003eTPS61090 boost converter from TI\u003c\/a\u003e \u003cspan\u003e.
